Specification of Letters Patent.

Application led July 5, 1916. Serial No. 107,596.

To all whom it may concern:

Be it known that I, DEMETRIO MAGGIORA, engineer, Italian subject, of 10 Rue du Quatre-Septembre, at'Paris, Department of the Seine, France, have invented certain new and useful Improvements in Gas-Generators; and -I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to acetylene or other gas generators.

An attempt has been made in the generator according to the presentinvention to make use of a closure which, while being watertight, permits of a fresh charge of carbid being easily introduced.

To this end, the bell of the generator is provided with a well or tube in which a pocket filled with water, forming a liquid seal. and a perforated pocket in which the carbid may be placed, can be lodged by turns. After introducing the carbid into the latter, thesystem is displaced in such a way as to bring the pocket full of water opposite to the well, thus forming a. hydraulic joint. Y Y

I will describe with reference to the accompanying drawing a construction in accordance with this invention but I do not limit myself tothe precise construction described and illustrated.

Figure 1 is a plan of a generator according to the invention.

Fig. 2 is a vertical section on the line I-I--I-I of Fig. 1.

Fig. 3 is a section drawn to an enlarged scale on the-line II-II of Fig,` 2.

Fig. 4 is a section on the line III- III of F ig. 3.

Referring to Figs. 1 and 2 the generator comprises a receptacle 1 having rounded edges and provided with a bottom 2 and a perforated cover for receiving two cylinders 3 and 4, provided with bottoms. A horizontal partition 5, placed against the bottoms of the cylinders forms, with a bottom 2 of the generator, a. chamber which is divided by a transverse partition 6 into two chambers 7 and 8. The chambers 7 and 8 are respectively in communication, by tubes 9 and 10 with the upper parts of the cylinders 3 and 4. Cocks 11 and 12, (see Fig. 1) place the' chambers 7 and 8 respectively in communication with the exterior. The cocks 11 and 12 are placed in communication with each other by means of a pipe in which is located a three-way cock, as illustrated in Fig. 1. This cock serves the purpose of establishing communication between the cocks 11 and 12 or between the holder and atmosphere, so that the generated gas may be per mitted to collect in the holder or may be taken from the holder and used while the generator is cutting off from the holder. The cylinder 3 receives the bell 13 of the generator, and this bell is provided. with a tube 14 in its right hand part..

The system of two pockets is shown on a larger scale in Figs. 3 and 4. One of the pockets, the pocket 16,.is perforated, while the other pocket, on the contrary, constitutes a seal. These two pockets are secured to a rod 17 which passes through the upper part of the cover, and which is guided in a sleeve 18 fixed on the latter. By rotating the rod, the perforated pocket or the seal 15 is brought opposite to the tube 14. Then the perforated pocket faces the tube 14, the part 151 of the seal comes into contact with the tube 14, thereby preventing upward displacement of the rod. Displacement downward is prevented by means of the plate 19, which can turn about an axis 20 on au eX- tension of the rod 17. When the seal 15 faces the tube 14, the rod can be raised, the tube penetrating into the sea-l which is of larger diameter, and the system is held in this position by making the plate 19 rotate about the axis 20 in such a way that the straight part 21 of the plate 19 comes into contact with the cover, and occupies the position represented by dotted lines in Fig. 2. It is, of course, to be understood that the generator is of the dip type, where the carbid is immersed in the water. At the time of the introduction of the carbid the pipe 4 is in the water, and to prevent the escape of gas, the pocket 6 is rapidly rotated to close off the piston 14.

The operation is as follows The cylinder 3 is lled up to a certain level, the perforated pocket is brought opposite to tube 14, and the charge of carbid is introduced. All that is required then is to rotate the system through 180 and to move the rod up again. The carbid is in Contact with the water, while the seal 15, which is full of water, forms a.v watertight joint between thetube 14 and the inside oit' the generator.

The gas generated collects in the top of the bell, and is led from there to"t`he apparatus in which it is toV ,be utilized by the tube 9, the chamber 7 and the cock 11. The apparatus may be provided with a holder, as shown 'in the constructional jform described, the bell 22 formingthe holder-being introduced into the cylinder 4. rfhis bell is provi'ded'at its upper paat witli'lalcross :piece 23 and itw'o y'screws 2a and '25 which `inay -be vclamped fby j am muts'Q and '27 The'shanks of th'e'screws -24Jand25 terminate iin stopsSZS Van'd v29, :and pass through Vholes in the :gen-

erator lcoyer. By `'suitably `adjusting 'the position `of the screws 24 and 25 the distance between lthe lstops yZ8 )and and 'thel generator `cover, fand consequently the imaximum 'liftof the bell 2:2 can be varied. llo work `the lbell-holder, a Ithree-Way cock is used, Ione 'of the `passages being connected with the service apparatus, and the two others with the cocks 11 and d2.

To charge the bell-'holdencommunication is established between the xpassages connected to the vcocks 111 and 12. The generator then iiflls the bell, `and when the desired quantity 'of .gas has been collected, -and the bell-'holder is lat its xmaximum lift, the 'coinmunication ibetween the generator and the bel-l is 'c'ut loft, and lthe bell-holder is -connected to thefservic'e apparatus. y

It ie,"`ot course, irto be lunde'r'stoocl that fthe rneasuring ldevice '22 is used when it is desired "to measureordispense a ,given quantity Eo'f-"gasso that when that quanti-ty has been measured, communication between the generator and 'holder is destroyed. When lit isfnot'necessary to measure thegas communication between the holder and generator is also -out ot, the :gas escaping from the pifpe19. y

The generator described `may lbe modified, vand the pockets may be lof fany 'suitable shape. fand Amay :be Yactuated in 'any :manner in l"order @to bring them opposite vto th'e welll.
